9. Check out your favorite. After you find a company with a rate and contract length you like, learn more about it. One way is to do an Internet search of the company. Place the company’s name in various searches beside these search terms: scam, rip-off and complaints. If the company has a troubled history, find out before you sign up. If only a few results come up from disgruntled customers, don’t worry. But if there are several dozen, continue with a quick search of the company’s Better Business Bureau record. And then, most important, return to powertochoose.org and below the name of the company, you’ll see “Complaint Scorecard” and “Complaint History.” Click on those links and learn more about the company.
Variable-rate supply plans, as the name suggests, have a rate that varies based on the market price of electricity. Seasonal and market fluctuations can affect supply rates. While variable-rate supply plans can allow you to take advantage of market-price lows, there is the possibility of paying for high supply rates when demand is at its peak. These plans offer great flexibility.
Compared to the rest of the nation, data from the U.S. Energy Information Administration which publishes annual state electric prices  shows that Texas' electric prices did rise above the national average immediately after deregulation from 2003 to 2009, but, from 2010 to 2015 have moved significantly below the national average price per kWh, with a total cost of $0.0863 per kWh in Texas in 2015 vs. $0.1042 nationally, or 17 percent lower in Texas. Between 2002-2014 the total cost to Texas consumers is estimated to be $24B, an average of $5,100 per household, more than comparable markets under state regulation. 
One desired effect of the competition is lower electricity rates. In the first few years after the deregulation in 2002, the residential rate for electricity increased seven times, with the price to beat at around 15 cents per kilowatt hour (as of July 26, 2006, www.powertochoose.org) in 2006. However, while prices to customers increased 43% from 2002 to 2004, the costs of inputs rose faster, by 63%, showing that not all increases have been borne by consumers. (See Competition and entry of new firms above for discussion on the relationship between retail prices, inputs, and investment.)
The PUC’s mission is to protect customers, foster competition, and promote high-quality infrastructure. In addition to regulating the states electric utilities and implementing legislation, the PUC offers Texas residents assistance in resolving consumer complaints. If you have a complaint with your electricity company you can go to the official PUC website and file an informal complaint.
